I wouldn't call 250-300 test/wk a 'cycle'.. I'd call that your base, and your 'cycles' would be when you either:
a) add other drugs in for a certain amount of time
or
b) add other drugs in as well as double the test dosage for a certain amount of time
for example;
maintain minimum of 250mg-300mg test/wk the entire time
for 3 months, double the test and add in 600mg npp (200mg 3x/wk)
back to 'base' test dose for 1-3 months
for 3 months, double the test and add 300-500 tren per week (either ace or enan)
back to 'base' test dose for 1-3 months
... and so on and so on.............
